Route 124 in Ruby and SapphireThe underwater area of the route.
The main path of the route begins as an east-west route from Lilycove, widening as it progresses east. Near the center of the route, the path turns to the south. At the mouth of the outlet near Mossdeep, a pair of islands play home to the Diving Treasure Hunter, who will exchange Shards for Evolutionary stones. South of the outlet, Route 124 becomes Route 126.
There are 16 spots to Dive along the route. Although not every spot is connected to one another via underwater pathways, most are, allowing Trainers to reach otherwise inaccessible areas of Route 124. Seaweed, the underwater equivalent of long grass, line the submarine passages of the route.
